I'd also ask the range to define it. I have chronographed my 597 with various makes and types of .22 ammo and have come to the conclusion that most embellish their velocity by a fair margin. CCI velocitor isn't even in the ballpark of its advertised velocity.

If you want some loads that were fairly high precision in the testing of my 597, for 10 shots off the bench using a high power scope, I obtained 1 1/2" -2" groups with Wolf MT and CCI "standard velocity". You will know these aren't anything special velocity wise as soon as they come out of the tube. Free floating your 597 will make it shoot with a higher level of precision if you care. I haven't found any rounds that shoot with a better level of precision than those two above (but then I don't have the money to blow on Eley tenex either). Also, federal #719 will work with nearly the same precision. As for a plinking round that will be okay at 50y and closer, automatch bulk works pretty well.

Just talked to them at the range. They consider anything over 1280 FPS to be high velocity. The reason they restrict it is they have a "bullet catcher system" that can be damaged by higher velocity rounds.

But 5.7 isn't banned.

What a ****y range. The indoor range near me allows everything including LMG's and GPMGs.

There are a variety of different types of .22 LR loads. They are often divided into four distinct categories, based on nominal velocity:
Subsonic, which also includes "target" or "match" loads, at nominal speeds below 1,100 ft/s (340 m/s).
Standard-velocity: 1,000–1,135 ft/s (300–346 m/s). Common velocities are around 1,125 ft/s (343 m/s).
High-velocity: 1,200–1,310 ft/s (370–400 m/s) per second.
Hyper-velocity, or Ultra-velocity: over 1,400 ft/s (430 m/s).
I'm a big fan of CCI Blazer ammo. It is inexpensive and accurate in my 22 guns.

No LR ammo should ever be banned from a range. What is their backstop made of, paper mâché? It sounds like they don't understand the limitations of their own equipment. You can't shoot CCI Velocitors, but you can shoot 9mm or .40S&W out of a long gun which would give you similar velocity with 3-4 times the weight!
